India has called on other countries to agree to a new code of conduct to prevent airlines from poaching each other’s pilots, engineers, and cabin crew without proper notice, cites Reuters report.

India has claimed that says foreign airlines are regularly hiring skilled staff from Indian carriers, which is hurting the growth of its fast-expanding aviation industry.

In a paper submitted to the International Civil Aviation Organization (ICAO) on August 1, India warned that this trend is creating a “vicious cycle”, forcing Indian airlines to constantly replace trained staff instead of focusing on expansion and improvements.

India, one of the world’s fastest-growing aviation markets, is already facing a shortage of experienced pilots, which threatens Prime Minister Narendra Modi’s goal of making the country a major global aviation hub. The recent Air India crash has further increased scrutiny on the sector.

According to government estimates, India will need 30,000 pilots in the next 15-20 years, up from the current 6,000-7,000, as airlines have more than 1,700 aircraft on order.

The aviation market is dominated by IndiGo and Air India, while global carriers such as Emirates, British Airways, and Lufthansa operate regular flights to India. The issue of poaching is not new, last year, Air India and Akasa Air publicly clashed over pilot recruitment within the country.

While India’s proposal to ICAO does not spell out exactly how the code of conduct would work, it stresses that without action, the constant loss of trained staff will cause economic damage and make it harder to reach the country’s target of 300 million domestic passengers by 2030.

ICAO, set up in 1944 to develop global aviation standards, will discuss the proposal at its upcoming triennial assembly.
